Applies to Dynamics 365 (online) version 9.0.x

With the October update to Microsoft Dynamics 365 for Customer Engagement, one of the changes we are making is to increment the version number to 9.1 for our online service. This change is part of our work to modernize the way we update Dynamics 365 by removing the reliance on the version number to indicate what changes are being delivered. This aids in a more seamless delivery of our service through our continuous deployment cycle and is an integral part of the evolution of our platform.

The update from 9.0.x to 9.1.x will happen automatically; you don't need to schedule anything.

In addition to the version number changing in the product, how we're referencing the service updates in our communications is getting a refresh. The Service Updates documented on our Microsoft Dynamics 365 Online releases page will still contain all of the fixes and changes included as part of a deployment, but you may see a difference in the "build" portion of the Version number (e.g. Version 9.1.0.xxxx) and what is displayed in-product.

The new version number - Microsoft Dynamics 365 for Customer Engagement apps, Version 9.1, Online - will begin rolling out in-product starting October 1, 2018. We will be gradually updating the product region-by-region through our global deployment processes, which is expected to take the entire month of October.

As a reminder, there are many things we are doing to enable businesses accelerate their digital transformation. Look for the ability to preview updates with a sandbox environment in advance of their release, starting in April 2019.
